Dream of friends and father

AOA. I saw a dream where we all friends went for a picnic. My father came from his job and he had a book in his hand. I asked my father whats this book about and he said its all about his job and pictures. I started to read that book and in that book i saw a picture of my dad and a guy.(i know that in my real life. we used to be friends. i’m trying to forget that guy but i can’t). I was shock when i saw that picture because that guy works where my dad works,he was junior and my dad was senior. So now when we all went for a picnic. At the beginning i was trying to do something that will attract him. He really didn’t knew who i am and he had few of his friends with him. One of his friend was flirting with and i kinda got angry. Now we all were going back to home from bus. Suddenly the bus was out of control and we had to go from other car. We sat in another car and that guy(the one who was in the picture) was sitting beside me. He was trying to be friends with me but i was trying to stay away from him. I really wanna now the meaning of this dream. JazakAllah.
